غسالات تقسيم متوسطة #1 | فولاذ مقاوم للصدأ 18-8 (1000 / عبوة)

Been using these lock washers on a few outdoor gate hinges that take a beating from wind. The 18-8 stainless steel looks like it won't rust, and the split design grips the threads nicely to keep everything tight.

Installed these on a small robot project and not a single fastener has backed out despite constant shaking. The stainless steel finish is clean and corrosion-free so far. Exactly what I needed for vibration resistance.

Picked up a thousand pack for some trailer repairs and the stainless steel resists corrosion way better than the cheap zinc ones I used before. The split design holds tight under vibration just as described. Exactly what I needed for heavy duty use.
